IMPROVBD MARTIGALE-RING.

The Schedule referred te in these Letters Patent and making part o f thesama.

To all whom 'it may concernI Be in known that I, wrman n. elem, ofBirmingham, in the county of New Haven, and State of Connecticnt haveinvented a new Improvement in Mzutingale-Rings; and I do hereby declarethe following, when taken in connection with the accentua:

nyinzgr drawings, and the letters of ,reference marked thereon, tothe afull, clear, 'and enact description of the same, and which said drawingsconstitute part of this specification, and represent, in

Fgnre 1, a, front view, and in Figure 2, a transverse section, on lino xx. This invention relates to an improvement in martingale-rings, theobject being the production of a' strong ring, neat in its appearance,and at a small cost; and consists in forming a ring from wood, or

other cheap material, to give form and shape to the ring, then applyingto such ring a flat ring ot' sheetnxetal, the width of the ring of metalbeing but little In order to the, clear understanding of my invention, Iwill fully describe the same, tts-illustrated in the accompanyingdrawings.

A is a ring, formed from wood, leather, or other suitable material. l

B isa ringof shcet -metal, formed so that the ,internal diameter will beless. than that of the principal ring, and the outer diameter greaterthan that of the principal ring. Then', in av common spinning-apparatus,I turn the metal down .over the wood, so that it will cover one side ofboth edges, as seen in g.-4 2,

exposing the other side.

This construction produces a very strong ring, and l one extremely cheapand light, inasmuch as the material of the body of the ring, which isemployed to give .an apparent solidity to the ring, is of very littlecost; and the metal may be very light, and stilly possess all thestrength requisite for martingale-rings.

'What I claim, as my invention, is

'lVIa'rtingale-rings, as an article of manufacture, the

body of' which is formed from wood or other material,

enclosed by a' sheet-metal ring, substantially as setforth. f
